Polycarbonate

Polycarbonate is the substance - is a colorless solid polymer plastic used in manufacturing in the form
of granules. It is durable, lightweight, optically transparent, flexible, frost is a good insulator and is very
durable.

From the chemical point of view, polycarbonates - synthetic polymers.

The special properties of polycarbonate due to its unique structure of the macromolecule.

Polycarbonate is a thermoplastic polymer (thermoplastic). This means that it recovers its properties
during solidification, no matter how many times it is not melted. Because of this polycarbonate can be
subjected to multiple processing that makes the material particularly attractive from an environmental
point of view.

 

About polycarbonate sheets

Polycarbonate sheets are made of polycarbonate pellets by extrusion and gained great popularity as a
versatile material with unique performance characteristics and a very wide range of applications.

 

Cellular polycarbonate


- A hollow polymeric sheet
with internal structure, which is a multilayered
structure, filled with longitudinal
jumpers - ribs.

Monolithic polycarbonate 

- Is a solid polymeric sheet with no internal
voids. Outwardly, it resembles ordinary glass,
only much lighter and stronger.

 

Advantages:

Ease

Cellular polycarbonate is 6 times lighter than glass, and solid - 2 times - it allows you to create
original designs lightweight, translucent surface to increase the area by increasing the width of
the passage of the bearing structure and implement the installation without lifting equipment.
Lightweight sheets to reduce the amount of load-bearing structures - this reduces the overall
cost of the object under construction.

Strength

Due to the structure of its molecules with unmatched performance polycarbonate impact
resistance - the panel out of it able to withstand several orders of magnitude greater weight
(wind and snow) load than glass. Additional structural strength relative to the weight of
polycarbonate gives numerous ribs, which form the mesh inside the panel.

Transparency

Monolithic polycarbonate is transparent and passes up to 90% of the world, higher than that of
ordinary glass. Polycarbonate panels are not transparent, but also possess a high degree of light
transmission - the most subtle of them miss up to 85% of the visible spectrum.

Heat and sound insulation

At the height of all polycarbonate sheets and polycarbonate panels soundproof cell in a 2-fold
higher compared with the glass of the same thickness, due to the air was full of emptiness.

Flexibility

cold makes sheets of polycarbonate material ideal for covering buildings with complex
geometric shapes: arched and vaulted construction and other geometrically complex building
projects.

Ease of cleaning

Polycarbonate sheets are easy to clean with plenty of water and 100% cotton cloth (may use
dish detergent or special funds, with the exception of ammonia, which leads to the destruction
of polycarbonate).

Easy to install

To mount the polycarbonate sheets are used convenient polycarbonate profiles that have the
same color scheme and mechanical properties.

Security

The blow polycarbonate does not fly the dangerous fragments, which also gives him an
advantage over glass.

Easy to handle

Polycarbonate sheets are handled perfectly ordinary cutting tools.

The temperature and fire resistance

Wide temperature range from -40 to +120 ° C.

Chemical resistance, and environmental influences.

Polycarbonate sheets withstand most chemicals and compounds, and retain their
characteristics over a long period of time.

Comparison with other materials

The values given for the sheet metal thickness of 4 mm. PMMA - polymethyl methacrylate,
polyvinyl chloride PVC, PET-G - polyethylene glycol, polystyrene, PS, HIPS - high impact
polystyrene, PC - polycarbonate.
